1. A wheel 2.00m in diameter lies in a vertical plane and rotates with a constant angular acceleration of 4.00 rad/s^2. The wheel starts at rest at t=0, and the radius vector of a certain point P on the rim makes an angle of 57.3 with the horizontal at this time. At t=2, find the angular speed of the wheel, the tangential speed and the total acceleration of the point P, and the angular position of the point P. 2. 3. for the speed I times the acceleration with the time to get 8 rad/s. The rest i don't understand so whatever help you could give will be grateful. Thanks.
